小型程控交换系统的可靠性设计

Reliability Design of Small Microprocessor-Controlled Switch System

文中在兼顾经济性的基础上给出小型程控交换系统的可靠性设计方案。对于有人值守和无人值守分别采用了多机联合控制结构和热备份处理机结构。文中还给出机间通信规约并简要地说明了软件设计方法和工程技术措施。产品样机测试和试运行的结果证实了该机的设计方案是正确、合理、可靠的。

Based on economic consideration, a reliability design of small microprocessor- controlled switch system is presented in this paper, the multi-processor and redundancy processor organiza-tion are designed for manual supervision and automatic supervision respectively, the protocols used in processor communication are also given. And the method of software design and engineering measures are described briefly. The test and run of the production prototype confirm that the reliability design is correct and resonable.
